SyntaxError at boot with esp8266-20160809-v1.8.3.bin

[humungus]

Hi,

I flashed esp8266-20160809-v1.8.3.bin to my esp8266-01.
When I boot the esp8266 now I get an error (full output below):
Traceback (most recent call last):
File "boot.py", line 5, in <module>
File "webrepl.py", line 6, in <module>
File "websocket_helper.py", line 1
SyntaxError: invalid syntax

Can somebody please tell me what the problem is? A syntax-error in boot.py?
I just flashed the .bin-file. I used the --verify-option and got an OK.
It seems I cannot use machine.xxx objects. Webrepl seems not to be working too.

I executed
>>> esp.check_fw()
size: 558748
md5: 66cd5e59c4f2236a5bc3b7c97789adc3
False

That function unfortunately is not documented in https://docs.micropython.org/en/latest/ ... y/esp.html but 'False' is probably bad?

Thank you!

False is indeed bad and indicates that the firmware image is invalid. Does your device have sufficient flash to accommodate it?

I had the same error when I switched from some older version of 1.8.2 to 1.8.3. I was also using something different at that time, not esptool. Cleaning flash and flashing the image with esptool solved the problem for me, so try running these 2 commands first (and replace the name of the image if needed):

Code: Select all

esptool.py --port COM3 erase_flash
esptool.py --port COM3 --baud 460800 write_flash --flash_size=8m 0 esp8266-20160809-v1.8.3-release.bin

Fortunately, everything is documented in troubleshooting section: http://docs.micropython.org/en/latest/e ... n-problems

My ESP8266 should have 512KB. The 1.8.3.bin-file has 558,8KB, so maybe it is to large.
I now flashed 1.8.2.bin which is 507,6KB. It seems to be working so far...
